 * Feature to support validation in components

 * 1. Catching ValidationException in the exception hook
 * 2. Storing errors in the component's error bag
 * 3. Sharing errors with views during render
 * 4. Persisting/restoring errors in the component memo
 *
 * Errors are only persisted for component properties, not for custom
 * validators that don't correspond to component properties.
